SPOT-PROOFING MECHANISM.

Specification of Letters Patent.

Patented oet. as, rare.

Application filed December 30, 1910. Serial No. 660,057.

Spot-Proofing Mechanism, of which the following is a specification.

My invention relates to improvements in mechanism for spot-proofing woolen, worsted, and other fabrics, which have, during finishing, received a luster.

By spot-proofing I mean a reduction of the luster to a degree which will, when water is sprinkled upon the dry faceof a fabric, prevent its leaving dark spots or marks when the water has disappeared and the fabric shall have become dry again, where it had previouslybeen rendered wet by the drops of water sprinkled upon it.

Heretofore, whenever spot-proofing has been attempted by the mills, it has been accomplished generally by steaming. The fabric, after having been finished in the regular way, was drawn a number of times over an open steam-box, such, for instance, as shown and described in my S. Patent Number 427069, May 6, 1890. This would remove from the finished heavy-Weight cloths-like over-coatings, cloakings, certain classes of mens wear goods, etc-such superfluous luster as would become spotted then water was dropped onto the fabrics face without impairing the handle of the goods too much. But, when passing light weight goods, like ladies broad-cloth, or similar fabrics over an open steamer, the steam issuing from it would penetrate through the entire fabric with sufiicient force and volume to remove not only the high luster on the face of the goods neXt the steamer, but it would take out of them also the remaining finish and handle, which the goods should retain in order to be acceptable to the trade. Therefore, the majority of light-weight fabrics would be, and still are, sentto the market with a full finish, so that they may handle satisfactorily; but they spot.

The object of my invention is to preserve the finish or at least, enough ofit so the goods will handle acceptably to the trade, and yet remain proof against water marks.

instead of putting steam to them, which goes clear throughfthe goods and renders light-weight fabrics slimsy 'andlifeless, be

cause it robs them of practically all their finish, I apply hot water, and in such a manner as to skin off, as it were, merely the outermost film of the imparted luster and finish, that is, not enough to take the life out of the body of the goods, so that they will still handle substantial and fairly firm after the uppermost and superfluous luster has been soaked off the outer surface. In addition, because it does not pass through and out of the goods again like steam, the water will restore to the goods considerably more weight, which is taken out of them during finishing, and which, heretofore, the goods would regain only after lying a long time in cool and damp storehouses.

The invention consists in the improve ments to be fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification and wherein Figures 1 and 2 represent opposite end views of so much of my machine as will enable those skilled in the art to understand the general principle of it, the cloth in Fig.

1 being in, and in Fig. 2 out of contact with the wetting-cylinder. Fig. 3 shows a front view of the entire face-wetting apparatus partly in cross section. Figs. at and 5 are details of the structure of Fig. 8, and Fig. 6 is modification thereof. Fig. 7 shows an end view of a part of the machine with the cloth in contact with the wetting-cylinder, when the machine is in operation. Fig. 8 shows the end opposite to that of Fig. 7 with the cloth swung out of contact with the wetting-cylinder, and an apron drawn down between the two, when the machine is at rest; while Fig. 9 shows an enlarged detail thereof.

Referring to the drawings by characters of reference 0; represents the cloth being treated, the same running in the direction of the arrows through the machine and con% tacting either with a wet cotton wrapper 1, lapped around the outside of a hollow cylindrical metal shell 2 of the wetting-cylinder D as in Fig. 1, or not, as in Fig. 2. When contacting with the wrapper l the cloth passes under a roller 7) carried in a bracket 0 fast upon a three-armed segment CZ made preferably in two parts, that are bolted together and can swing upon the necks or jourthe machine and revolving in brackets Z fastened to the main frames A. At one end of the shaft (Fig. 2) is keyed a spiral gear m meshing with another spiral gear at fast upon a shaft having at its front end'a handle This shaft 0 is revolubly mounted in a bracket 4" fast upon the post B of the arched top frame C, and in a bracket 3 fast upon the cap 25, on one of the bearings 42, which are fastened to thefront of the main frame A, and in which bearings o rest the necks or the journals '6 of the stationary interior heating-cylinder fheretofore referred to. (Fig. 3.) Thus, when turning the handle 39 the segments cl will swing around the journals 6 of the interior stationary heating cylinder 7. The shaft 0 carries also a notched wheel or head 10 (see Fig. 8) and close to the brackets and upon an extension sf of the bracket 8 swings a ball-arm a with aheavyballz at its end, which ball-arm has on its lower side a catch, or nose 1, fitting any of the notches in the periphery of the head w, so that, by first lifting the bell-arm a, high enough to disengage its nose or catch 3 from the notched head 10, the operator, by turning handle can swing the segments (5 into any desired position and then lock them there, by dropping the ball-arm z with its catch g again into engagement with the notched head to. V

' As the cloth a is threaded between the rolls 6 and b, the operator when turning the handle 39 will swing it from the position shown in Fig. 1, to that shown in Fig. 2, the roll 7) then holding the cloth high,.so that it cannot flop down on to the wettingcylinder D.

-It ,will be seen that during the wetting operation the cloth passes over the upper surface of the wetting cylinder and is held in'engag'em'enttherewith by the tension and guiding roll '6, which is located on the upper face of the cloth, in which. position of the segment the lifting member Z2 is beneath and out of contact with the clothhen the segments are rotated'towardthe rear of the machine the tension of the roller is lifted to. relieve'itspressure on the upper surface of'the cloth, and the lifting member engages the under face of the cloth whereby the latter islifted clear of the wetting cylinder and moved over the same toward therear of the machine so that such parts of the apparatus as are covered by the cloth during the wet- V ting operation are made readily accessible.

, [Referring to Figs. Band 5, it will be noticed'thatthere is afclearance, or slight air space between the cylindrical metal shell 2, and the stationary interior heating cylinder 7, so they cannot touch when the shell 2 is set in motion. Heating steam is admitted to the cylinder f, through the pipe 7, the water of condensation escaping through a siphon f screwed into the extension 0, at 6 where there is a small pocket or chamber a to which is screwed a two-way elbow f. The cylindrical shell 2 carries at its ends heads 3 which upon their necks carry rings 4 forming one-half of a set of ball-bearings, the other halves of which 5, fit into heads (3 fast upon the journals 6, of the stationary heating-cylinder The heads 6 also have end-thrust ball-bearings 7 inserted into them, so that if the machine should ever get out of level, and the wetting-cylinder should lean toward one end or the other, the cylindrical shell 2 will still be able to revolve freely and without any excessive degree of friction at its ends.

Directly below the wetting-cylinder D is placed a trough S resting upon the brackets 9 fastened to the main frame A. Bosses 10 are cast on the trough at its ends, which bosses have studs 11 screwed into them; and upon these studs swing bell-crank levers 12 which carry on their short upper arms a roll 13 while their longer, or lower arms are provided with weights 14. A stud shaft 15 carries a hand wheel 16 at the end and has a pinion 17 keyed to it, which meshes into a gear 18, fast upon a cam shaft 19, extending across the machine, with bearings in the brackets 9 on the main frame. On this shaft 19 and directly under the bell-crank levers 12 are keyed cams 20, so that by turning the hand-wheel 16 the perator can swing the bell-crank levers 12 on the studs 11 so as to raise them, and by so doing, can throw the roll 13 mounted in them out of contact with the wetting-cylinder D. Or, by turning the hand-wheel 16 still farther he can cause the weighted bell-crank levers 12 to drop, so as to bring the roll 13 into contact with cylinder D, and according to the number of weights 14 employed by him, it may press more or less hard against the cotton wrapper 1 lapped around the shell 2.

As the trough 8 is filled with water reaching high enough to touch the cotton wrapper 1 around the shell 2 of the wettingcylinder D, this wrapper 1 can be made to absorb and carry up more or less water, the amount varying with the number of weights the operator chooses to hang on to the levers 12. There is placed in the bottom of this trough an overflow pipe 121, having two openings on top, a higher one 122, and a lower one 123. Upon the opening 122 is screwed an adjustable crown, or level-ring 124, and upon the opening 123 may be placed a detachable cap, or shut-off 125. If the wrapper 1 lapped around the shell 2 is a lltl long one, which causes the diameter of the wetting-roll to be correspondingly larger than when a shorter Wrapper is used, the operator turns the crown 124 down a little and reduces thereby the level of the water in the trough, so that the larger diameter roll will dip no deeper into the water, than would a smaller diameter roll, built up with a shorter wrapper, in which latter case the level-ring 124: would be screwed up correspondingly higher, to allow the same dip of roll into the water, as first had with a larger roll. After regulating the level of the water in this manner to let the overflow pass away through 121, the cap 125 is placed upon the opening 123 during all the time the machine is in operation. When it is desired to stop it during the noon hour, or at any time during the day, the cap 125 is removed, whereupon the level of the water will. sink to the top of the opening at 123, that is to say, the water will cease to contact with the bottom of the wetting-cylinder and cannot fill it up with moisture at one point during this time. The cam shaft 19 is then turned by the hand-wheel 16 to throw the roll 13 also out of contact with the wetting-roll body, whereupon the heat from the heating-cylinder f will soon dry the cotton wrapper 1. lVhen wishing to start up again to do some more spot-proofing, after the cotton wrapper has become dry, the cap 125 is put back once more upon the opening 123 until the level of the water in the tank 8 shall have risen enough to flow over the upper edge of the level-ring or crown 124, that is to say, shall cause the cotton wrapper 1 to contact once more with the surface water in the tank. Then the wetting-cylinder has to be revolved around a few times, to make the wrapper re-absorb the water, and to load it uniformly with it. The operator has to throw the roll 13 once more against it, which, pressing evenly across its surface, squeezes all surplus water out of the wrapper 1 and insures a uniformly wet surface for the cloth a to lie up against when the machine is set in motion.

To turn the wetting-cylinder conveniently, its metal shell. 2 carries upon one end a gearring 21, the teeth of which match those out into two small gears 22 made fast to two pinions 23 all of which turn loosely upon studs 24:, projecting out from a bracket 25 fastened to the lower end of a sliding bar 26, moving vertically in a bracket 27 fastened to the post 13 over the main frame. Centrally and horizontally mounted in the bracket 25 is a short shaft 28 having at one end a crank handle 29 and upon the other end a pinion 30 (Figs. 2 and 3) which meshes with the pinions 28. On top of the bracket 25 is a handle 31 for the operator to press down on, when he desires to push the sliding bar 26 down into the position shown in Fig. 3, or when he wishes to raise it to the position shown in Fig. 2. When pushing it down, as shown in Fig. 3, the gears 22 will mesh with the teeth of the gear-ring 21 upon the end of the cylindrical shell 2 which, as soon as the handle 29 is turned will begin to revolve. A counterweight 32 passing up and down through an opening in the bracket 27 and connected by a chain 33 (which runs over idlers 84 mounted in a bracket 35) to the sliding bar 26, permits the operator to push the gears 22 into and out of connection with the gearring 21 with the greatest ease. This apparatus for turning the wetting-cylinder is not only a very convenient means when beginning to wet the wrapper 1 preparatory to starting the machine, but it is practically indispensable when a new wrapper has to be wound on to the shell 2 for the first time, which, to insure a smooth padding, has to be done under a very considerable strain and tension. If I did not provide the means here described, the wetting-cylinder would have to be taken out every time, and placed in some sort of winding apparatus, before a smooth covering could beproperly put upon it.

The water for the tank 8 when first starting amachine, can be supplied by piping a water connection to it, or it can be filled by pouring a few pails of water into it. Once filled the exhaust from the inner heating cylinder f is more than sufficient to keep it filled to overflowing, and to keep it also near-the boiling point at which temperature the water shows far greater avidity for soaking into the cloth than it does when it is cold. The exhaust, after reaching the twosvay elbow f when not wanted for heating the water in the tank 8, in which case it passes into it through the pipe f, can be turned away through the pipe f both of these pipes being provided with suitable valves for this purpose.

The tank 8 is provided in front and rear with guards 86 for confining the vapor arising from the hot water contained therein close to the wetting-roll D and preventing this vapor from spreading too much around the machine. 1

Referring to Figs. 7 and 8, of the drawings, I have shown there the manner of handling the cloth, as it goes to the wettingcylinder D. In passing from the cradle E upward the cloth ct travels over and under two round stationary bars 37 which form the ties for a couple of trolley trucks 38 running freely upon a pair of rocking-rails 89, one at each end of the machine, and located directly under a couple of overhead arms F fast upon the tops of the post B secured to the main frames A of the machine. The rails 39 near one end are pivotally connected at 41 with hangers 40 de &

pending from the overhead arms F and at the other end they are shackled to links 42 pivotally connected to crank-arms 43, which are fastened to a shaft 44, which extends across the machine and carries upon one end a hand-wheel 45, by turning whlch the rails 39 may be raised from the positlon shown .in Fig. 7 to that shown; in Fig. 8, and vice versa. The links 42 have semi-circular notches '46 cut into them, which fit the round shaft 44 when the links are swung I upward, and as in Fig. 8 a little beyond their vertical central line, so as to lock them in that position. When thus raised into this position, the trucks 38 upon the rails 39 will roll down the incline until one of the truck wheels will abut against the stop 4'7 and arrest it, whereas, if the hand-wheel is turned to lower the links 42 into the position shown in Fig. 7 the trucks will roll back again.

VVhen'the machine is running, as shown in Fig. 7, and the operator desires to stop it,

he first swings the segments (5 into the pothem during their retreat from'the position shown in Flg. 7 and thus the loose loop of cloth whlch would form and hangdown between the segments, when they are thrown up, and the truck-bars overhead, if they remained fixed in the position shown in Fig.

'7, is taken up as fast as the automatically ret'reatin trucks can travel. The wei 'ht of the trucks and the momentum they gain thereby in their downward travel is such as to take care of the loose fold of cloth that might otherwise hang down over the operators head when the segments are turned up in order to free the cloth (0 from contact with the Wettingcylinder D. The operator is thus not annoyed when standing between the cradle E, and the front of the wettingcylinder D by a bag of cloth coming down a and enveloping him, and thus seriously interfering with hiswork every time he wishes to break contact of the cloth with the wetting-cylinder. 7 7

When the operator, for whatever reason,

- has to stop the machine with the cloth threaded as shown, and removed from contact with the wettin -cylinder, the vapor b a rising from the bared portion of the wetting-cylinder would, in a very short time, cause that portion of the cloth lying in'close proximity thereto to become darker in shade, than any other'portion of the cloth, already past the cylinder D, or yet to pass over it. To prevent such 'shading'I employ preferably a rubber covered apron 48, rolled upon a'roller 49, which is mounted in a bracket '50, and draw the same whenever the machine has to stop, between the cloth, after the cloth has been raised away from the cylinder D, and the cylinder. At the lower end of the curtain is attached a Hat metal bar 51 of sufficient weight to keep the apron taut when drawn down, as shown in Figs. 8 and 9. At each end of it is a U-shaped channelpiece 52 for guiding the ends of the curtain bar, a bracket 53 fast upon the gird A holding it rigidly at the proper angle, so that the curtain shall touch neither the cloth nor the cylinder D but will form an effective shield between the two to prevent any of the vapor from the bared cylinder D reaching the cloth.

l/Vhile in Figs. 1 and 2 I have shown but two rolls, Z) and Z), mounted in bracket 0 attached to the segments d, I have added athird one 0 as shown in Figs. 7, 8 and 9, to enable me to thread the cloth in two different ways, one of which gives more and the other giving less friction to the cloth at that point, as the case may require.

In Fig. 6 I have shown a modification in which cloth may be treated which requires a greater amount of loading with water than ordinarily demanded, in which form a roller 13 mounted in a swinging lever 12 weighted at one end as at 14: contacts with the wetting roll, and receives from it such moisture as has not been absorbed by the cloth passing over it before contacting with the roller 13, which roller 13 is pressed against the wetting roll by the weights 14. By its contact with the wetting roll D it is not only revolved in a direction opposite to that in which the cloth runs, but it gathers moisture from the roll D and deposits the same upon the cloth thereby adding not only additional moisture but wiping the moisture previously received by the cloth by contact with the roller D into the surface of the cloth, thus causing the cloth to take up more water than it would were the roll 12 omitted.

It is obvious that the covering of the wet ting material being of absorbent material that it will still contain some of the moisture taken up after it has passed the cloth, and that some of this remaining moisture will be collected by the roller 13 and transferred to the part of the cloth which has passed the wetting cylinder.
